我们证明了自适应延迟反馈控制系统的动态特性,利用离散时间自适应控制方法进行详细的分析。特别是,系统表现出奇异性,如幂律衰减的瞬态时间和几乎为零的有限时间李雅普诺夫指数的分布。我们可以解释这些结果的特点,这样的系统具有(1)一个雅可比矩阵的单位特征值在整个相空间,(2)参数接近稳定边界证明是相同的(非自适应)延迟反馈控制。
We demonstrate the dynamical characteristics of adaptive delayed-feedback control systems, exploiting a discrete-time adaptive control method derived for carrying out detailed analysis. In particular, the systems exhibit singularities such as power-law decay of the distribution of transient times and almost zero finite-time Lyapunov exponents. We can explain these results by characterizing such systems as having (1) a Jacobian matrix with unity eigenvalue in the whole phase space, and (2) parameters approaching a stability boundary proven to be identical with that of (nonadaptive) delayed-feedback control.
